| Resumo | |
Wildfires happen in almost all biomes worldwide, and they can cause profound environmental and socio-economical impacts. Fire regimes are emergent properties of a complex system (e.g., climate-vegetation-fire interactions), which are influenced by many factors, such as climate warming, geography, vegetation, and human activity. In particular, anthropogenic land use can alter wildfires' incidence, size, season, and severity. Consequently, it is paramount to understand fire regimes to characterize similar spatiotemporal wildfire activity between natural or human ignition dynamics. This study proposes a framework combining complex networks and machine learning to classify similar wildfire regions. From global satellite data over the past two decades, we extract graph-based features to characterize spatiotemporal fire regimes from different Tropical/Temperate/Boreal forests around the globe. With the extracted high-level features, we can classify how dynamically similar the wildfire regimes are between six studied regions: Amazon basin (AMZ), Australia (AUS), northwest U.S. (NUS), northeast China (NCN), and central Africa (CAF) and Asia (CAS). Results from well-known classification algorithms indicate that the AMZ and CAF wildfire dynamics are more similar than the other regions. Although we found that wildfires in NUS are more similar to the AUS regime, NUS has around 33% of similar behavior to wildfires in the AMZ. (AU) | |
